Police in Scotland have urged employers to be “flexible” with staff as extreme weather continues to cause major disruption to travel routes.
An estimated 1,000 vehicles were stuck on the M80 overnight and road crews were working to free those which were still there on Thursday afternoon.
Drivers reported being stranded for up to 13 hours, with some spending the night in their cars, and others abandoning their vehicles on the motorway.
Now employers are being urged to allow staff to work “flexibly” to avoid further disruption to routes.
Superintendent Helen Harrison said: “We continue to deal with a number of challenging incidents right across the country and the response from our officers, staff and those of our partner agencies has been outstanding.
“Our advice has not changed – avoid travel in the affected areas and keep a close eye on the Met Office updates and from the authorities across Scotland.
“If you can postpone your journey in affected areas until after the amber warning ceases I would urge you to do so.
“We’d ask employers to continue to allow staff to work flexibly.”
The comments come after Transport Minister Humza Yousaf told Reporting Scotland he would be holding talks with employers after workers became stranded while travelling for work.
Other major roads such as the M74 and the M876 also faced severe disruption.
